->Even a BIG compressor would be 'small'.  There's not enough cu ft available
->run mobile engines, so they compress the NG to LNG (Liquified Natural Gas).
->IIRC that takes about 4,500 PSI, and needs discharge cooling around -170
->degrees to start the condensation to a liquid.

4,500 psi?  -170 degrees?  Sounds like my ex-wife on a bad day.  But, that's
a significant problem to overcome.  I can see why the few vehicles powered
by LNG are all commercial or public.  In Providence, only the gas company
and some public transportation buses run on that.

->The process is very similar to LOX, Liquid Hydrogen, and Liquid Nitrogen.

Yep.  Rocket science, apparently.

->Easy to understand why LPG has such a lead...

And will for quite a while.  Fuel cells are making some big strides.  Maybe
in ten years..
